SEO has been around as an industry as long as Google has existed, and possibly even before. As long as there have been, and as long as there will be search engines, there will be people looking to conform to whatever algorithm they use to rank content. Some will pursue every legitimate technique under the sun, while others will turn to the dark side, employing techniques with short shelf lives, high efficacy, and perhaps even a hint of exploitation.

As a marketer, I have – and you no doubt have – encountered dozens of businesses, brands, services, and consultants that will promise a wide range of various SEO services. I even provide some myself. As varied as the techniques are, there are dozens of providers for every technique. Link building is foremost among them, and the market is absolutely saturated.

You know what? Saturated doesn’t even cover it. Saturated makes me think of a towel that got dropped in the tub; it’s wet but it’s nothing you can’t handle. If you dropped a towel in the tub, picked it up, and it ran like a faucet for three days, now that is what the link building market looks like.

What I’ve done below is compiled a list of as many link building products, services, tools, and apps as I can find. By the time I’m done, this should be the biggest list available on the Internet. To make sure it’s great, I need a little help from you at home. If there’s a link building tool you use that I haven’t added to this list, let me know in the comments so I can add it. Likewise, if one of the tools below has been closed down or removed, point it out so I can scrap it from the list.

Disclaimer: I make no claims as to the utility, safety, or viability of any of these tools. As with any list of this size, there’s no way I could have used all of them, and there’s no point. Heck, many of them probably use the same tool in the back end, resold or repackaged with different branding. I don’t know, and I’m not making claims to know. Use any link building tool at your own risk. As with any form of link building, understand how the tool works, what quality links it is providing you, and how you can do what it does on your own should you desire to do so.

The List

Here’s the list! Have at it. The tools are sorted into groups based on their rough purpose:
